I'm considering buying one of the CUCV M1028 military trucks and swaping the Dana 60, 14 bolt, Th400, and NP208 all into my 72 K5. I'd like to hear from those who have done the swap and any input on what problems or snags I might hit along the way. It seems like a easy way to have a bombproof K5 but I would definitely like to hear from people much more knowledgeable than myself. Thanks in advance

Should be a relatively straight forward swap. May have to adjust tranny/t-case cross-member location, but that is easy. As far as being bomb-proof, all of the CUCV components are good. But there are two things that could use improvement.

1) The NP208 t-case is a chain driven case with an aluminum housing. Chains stretch and break, and aluminum housings crack. A gear driven, cast iron cased NP205 would be a stronger alternative, but the low range might not be as deep as the NP208.

2) The CUCV 14 bolt might be equipped with a "Gov-Lock" limited slip. These are good units when new. But when they have been worked hard over many years, they have a tendency to have the clutch plates disintegrate and drop pieces into the diff fluid. Had this happen to me.

Overall, I think you have a pretty good plan with this drivetrain swap.

I bought the M1008 pickup to do just that . I had purchased it from a military base here in Columbus, Ohio a few months ago. Took like a month just to get a civilian title for it anyways. I wanted to drive the truck around a bit to be sure all components were working correctly. The 39,000 mile truck seemed to run and drive perfectly 6.2 motor ran good as well. The one problem was itís super slow but definitely built to pull down a house lol.
It to has the 400,208 & the 456 gears. Thang is Iíve been using the hell out of it! Iíve changed all the fluids in it and the dry rotted tires. If something happens to the 6.2 is probably when Iíll do the swap.
Till then Iím
